End of Support: This addon will no longer be updated.

Intelligence to a new level!

Sninctbur's Artificial Intelligence Improvements, or SAII for short, is a powerful AI improvement modification for Half-Life 2 NPCs, designed as a more mod-compatible alternative to larger mods like iNPC.

Features

• Patrolling: While out of combat, NPCs will automatically wander around in search of danger, fresh meals, Freeman, and what-have-you. If their ammo is low, they will take this time to reload as well.
• Threat Detection: NPCs are no longer (as) oblivious to danger! When an idle NPC or its general vicinity gets shot at, they will begin pressuring the shooter if they are within a stone's throw of them, or try to move evasively otherwise. Unarmed NPCs will run for their lives.
• Sound Detection: Might it be a footstep, a pot hitting the ground, or a massive f[spoiler] [/spoiler]king explosion, NPCs can be alerted by noise around them, and will lnvestigate the source. Louder noises have a larger range of influence, and if the sound is loud enough, they will move much quicker to the source.
• Extended Vision: All NPCs can spot enemies from much farther away. Watch your head!
• Summoning: Upon confirming their target, NPCs will call for help from all of their allies in a large radius around them. This may lead to a chain reaction ending with the entire map getting alerted!
• Enhanced Proficiency: By default, all NPCs are much more accurate with their guns than usual.
• Full Configuration: SAII is fully modular, meaning that each of the previously mentioned features can be modified or turned off. A configuration menu is available under Options > Sninctbur's Tweaks.

Q&A

Q: What NPCs does this affect? A: SAII affects all of the Half-Life 2 NPCs and numerous types of custom NPCs. It doesn't add anything new to the spawnmenu. Some custom NPCs use a hardcoded AI system, so they aren't affected. If you only want the HL2 NPCs to be affected, you can enable "Only Affect Default NPCs" in the configuration menu. Q: What mods is this incompatible with? A: SAII is designed to cause as few compatibility issues with other mods as possible. However, it may not play as nice with other AI modifications and a few custom NPCs. Q: Can you add <feature>? A: Please post your idea in the pinned Suggestions thread below. Be aware that if it's more of an AI "overhaul" than a simple modification, I probably won't add it. Q: Can you make medics heal their friends? A: They already do this. Q: Look for the lowercase 'L' and you will be ki-- A: Get off of my property. NOW. Q: I have a question that isn't here. A: Feel free to tell me about it in the comments! I don't bite. Q: May I use code from this addon in my addon? A: You are free to duplicate, modify, and upload code from SAII as long as you don't take credit.
